Re: test to post image(post good image)

That won't work, HTML isn't allowed in the forums to avoid spamming. Just use [url] bbcodes, anyone interested would click anyway.

Re: post your game ideas

I was thinking of a more general solution for the most video modes we already have. At the beginning of each raster line, it could be checked whether we are at the next section start (a single cmp) and if yes, the pointer is incremented and an init routine for that new screen section is started. Tha...

Re: post your game ideas

If you need two separate horizontal sections below each other, you have to tweak the mode 3 code the way it starts over with a second screen start address after some raster line. That's not so hard to do. I strongly vote for having a generic raster line API in mode3, which allows you to setup a numb...

Re: Some questions about uzebox

It is said there is a internal bootloader in atmega644 chip(ISP works depend on), here the bootloader is the uzebox special bootloader,not the original one? The ISP doesn't need a bootloader. It even works on chips without bootloader support (like the ATtiny series). The ISP is some special unit in...

Re: Protecting the bootloader when using ISP

The boot loader resides in the same flash as the normal program. From ISP's view, it's just not there. There is no such command as "page erase" on the ISP side either, only "chip erase". :(

Re: Color palette trouble with GIMP

I had trouble with gimp's raw output, too. Instead of PNG-8 I chose PCX, however, and wrote a tiny parser for that simple file format

It's so simple it could easily be rewritten in any programming language if you don't like Tcl.

Re: Mame cab build.

It would be nice to have a cabinet which can be folded so one could it transport to conventions.

Same problem here. I'm pixeling sprites when I'm in that mood - oddly enough, that was the start of Würgertime and all my motivation.

Re: Any new games

Well, Würgertime isn't finished yet. And I have some urge to finish it but I'm stuck.

Re: How to compile from source?

I get the same error with avr-gcc 4.8. This compiler optimizes much different than previous versions of gcc and it is very picky about subtle programming errors like these. ALL of these const arrays need an additional "const"; even at the expense of e.g. having a const char* const, which the casual ...
